The plate member e includes also example. somepreferred embodiments of the a claw 9' which operates a cut out plungerP to present invention. f stop the machine, the cut out plunger P beingFig. 1 shows in elevation a tabulator printing mounted in a stirrup 70carrying a horizontal lug machine including swingingly mounted tabulat-Z adapted to be engaged by the claw 7 while being printing actions, anda total taking at-.- tween the stirrup and a fixed part of the machineindicated at m is a spring 11.. In operation the arm h reciprocates andcarries with it the plate g whereupon the plate e, from Which'the claw chas been removed by the arm b, falls forwardand the claw :i engages thelug l. Consequently, on the next reciprocating movement of the arm h thelug Z is pulled with the plate 6 and the arm h, and through the agencyof the stirrup and spring is the plunger P ismoved.

Thereby a clutch, controlling communicationthe attachment and theplunger a descends that j the claw becomes operative.

Such an arrangement provides automatic stopping means which cause astoppage of the machine when there is no card in the machine.

,A tabulating machine. with this attachment and with means for operatingthe cut out plunger permits atotal operation to be taken when a changeof designation in the card occurs, as

explained in British Patent Specification N0. 271,935, and a stopping ofthemachine.

. A preferred form of mechanism according to the invention for operatingthe cut out plunger after a, predetermined numberof operations in themachine, comprises a counting device in the form of a nut member 1, seeFigs. 4,5, 6A, 8 and 12, that is to say, it is a rotatable member movable laterally during rotation. I

0n the periphery of the nut member 1, as

clearly shown in Figs. 4, 6A and 8," is a cam 2 A hereafter referred toas a cut out cam, the

member 1 being in telescopic engagement with a ratchet wheel 3 (Fig.12), conveniently by forming on the ratchet'wheel two diametricallyopposite posts indicated at 4, preferably of seg- V mental form, whichstraddle the nut andengage opposed flat sides thereof, as most clearlyshown in Figs. 2, 7-, 8and l2; Thereby relative angular movement betweenthe ratchet and the nut member '1 is prevented. The ratchet wheel 3 iscarried on a sleeve 5,see Figs. 3 and 4,. which is free to rotate on afixed spindle 6, but is fixed against lateral movement.

The sleeve is extended to form the arbor of a coil spring 7, one end ofwhich is fixed to the sleeve and the other extraneously anchored, forinstance, as at 8 to a supporting plate 9 carried by the frame of themachine.

The spindle 6 includes a threaded portion indicated at'6a, Fig. 4, onwhich the'nut member is mounted. a

The coil spring 7 is tightened during the step by step rotation of theratchet wheel 3 on the.

latter being actuated by a pawl 10, Figs. 6A, .7 and 12, in a mannerhereafter referred to,'until the actuating pawl 10 and the co-operatingdetent 11 are rendered inoperative by the cut out.

cam 2 on the predetermined lateral movement of the nut member beingaccomplished The adjustmentof thenut'member 1 along the threaded part ofthe spindle 6a away from the operative position in which it prevents theactuating pawl l0 and the detent 11 from acting, determines the numberof operations in the machine permitted before themachine is stopped.

The cam 2 is set in its position of adjustment on the spindle throughthe agency of a second threaded member indicated at 12 (Fig. 2) andhereafter referred to as the setting drum" which is mounted on thethreaded part 6a of the spindle, and which is disposed on the spindle tolimit the'retraction of the nut member from its operative position.

The setting drum has on its periphery 13 numbers which indicate, as moreparticularly hereafter explained, the number of operations in themachine, as determined by each position of the drum on the spindle,which will be performed by the machine beforeit is stopped.

The back of the-drum is provided with a shoulder or stop 14 (Fig. 4)which acts as a stop for the nut member 1, thereby limiting itsretraction according to the disposition of the setting drum on thespindle 6.

Supposing now the machine is operating and feed pawl 10 moving theratchet 3 in an anticlockwise direction, it will be seen that as" thespindle 6 is held against rotary movement the nut member 1 is advancedto the actuating pawl 10 and detent 11, the nut member 1 being forced tomaintain its angular relation with the ratchet ratchet, and the wholemechanism is ready for the next advance .of the nut member;

The actuation of theratchet 3 through'the agencyof the pawl 10 isefi'ectedby employing the following construction.

The pawl10 is fulcrumed at one end 01' an oscillating lever 15 which-ismovable about an axis preferably concentric with the ratchet 3,

the other end of the lever being connected to a telescopic rod 16actuated from cam gee-r17 as clearly shown in Fig. 7, the cam beingmounted on anysuitable shaft of the machine so that the actuating pawl10 moves the ratchet one tooth forv each revolution of themain shaft ifthe machine is to be stopped after a given number of revolutions. p

Thefeed pawl 10 is conveniently in the form of a bell crank; .50 also isthe detent 11 which latteris pivoted on plate 9, an d the free arm ofthe feed pa'wl'lO is crankedjover as clea'rly'shown in Figs. 2 and 12 toinclude a part 10a which after slight movement of the pawl 10 engagesagainst the free arm of the detent 11," the cranked portion beingextended to form a handleylob bywhich the feed pawl and detent can bereleased by handoperation from the ratchet when desired. u

The-partlOa of the pawl 10 is automatically operated by an arm 18.(Figs. 6A and 13) hereafter" referred to as the obstructor arm, its

function being to engage the feed pawl 10, and

free it from the ratchet, the operation of the feed pawl causing similaroperation of the detent 11 as just explained by reason of the r crankedover portion 10a of the pawl 10 engaging. across the free arm of thedetent 11.

'The obstructor arm 18, Fig. 13, is supported on a, spring-controlledlever 19 pivoted on pin 20 carried by plate 9 and is rocked about itspivot upon the arm n being reciprocated in the manner aforesaid from theeccentric To this end the plate g carried by the arm h is provided witha bearing 21 for a pivot pin- 22- which forms a support for a v U shapedclaw member 23 including the claw 24 more particularly hereafterreferred to, the claw member 23 in turn' beingpivotally connected at 25to the lever 19 aforesaid. Thus, movement of the arm 71. impressed fromthe eccentric E through the agency of the plate g andpin 22 causes asimilar movement in the U shaped member 23 whi'ch is communicatedthrough the pivot 25 to "the lever 19. This rocking of the lever 19about its pivot 20 is transmitted to the obstructor arm '18. i V

Now in the position shown in Fig. 2 these reciprocations of theobstructor arm 18 will merely cause it to pass to and fro over thecranked portion 10a of the feed pawl. The lever 19 is in slottedengagement as indicated at 19b with its pivot 20 so that it can bedisplaced axially to an extent whereby the to and fro movement of 'theobstructor 18 occurring as just explained will cause the nose oftheobstructor arm 1'8'to engage the portion 10a of the pawl and causethe pawl 10 and detent 11 to be rocked clear of the ratchet, therebyfreeing the ratchet so that it may be returned to resetting positionagainstabutment 14 of the setting drum 12 under the conserved energyderived from spring '7.

This movement of the lever 19 and the consequential displacement of theobstructor arm to renderthe feedpawl and detent inoperative,

is caused by the cut out cam 2 in a manner now to be described. I

Resiliently connected to the lever 19 by means of a spring 26 is asubstantially horizontal arm 2'7 supported by spring 27a, see Figs. 2, 8and 13, which arm is pivoted at 28 in' plate 9 and carries an abutment29.

The'arrival of the cut out cam 2 to operative position when it engagesand lies on the abutment 29 causes arm 27 to be depressed or displacedto the horizontal position shown in Fig. 8. This displacement of the armthrough the agency of the spring 26 causes thelever 19 to be pulled downin relation to its pivot 20, whereby on the next-forward movement of theobstructor arm the feed pawl and detent are retacted from the ratchetand a resetting 'of the mechanism effected. I

At the same time the claw 24 hereinbefore referred to also becomeseffective. With the lever 19 in its raised position the claw 24 on the Ushaped member 23 moves to and fro over a lug 1 on the stirrup Icof thecut out plunger P but when the lever 19 is depressed by the cut out cam2 depressing arm 2'7, the U 'shaped'member comes down with it, and theclaw 24 on the next reciprocating movement derived from the cocentric Eengages the lug Z' and operates the cut out plunger P. Thereupon themachine is stopped after a predetermined number of operations ascontrolled by the setting'of the drum On the completion of the resettingoperation the lever 27 is returned to the position shown in Fig.2 byspring 27a. Such movement through the agency of a pin 19a; carried bythe lever 19 and engaging the arm 27, causes the lever 19 to be raisedwith the arm 2'7. Thereby obistructor arm 18is raised and the pawl 10and detent 11 freed toreturn to engagement with the ratchet 3.

To prevent premature return of the pawl and detent, means are providedto delay the return of arm 27 tonormal position after the cut out cam 2has moved from pin 29. To this end the noise of arm 2'7 is engaged bymeans conveniently in the form of a pin 2717 on a'latch 27c;norm'allylying against lever 19 and pivoted at 27d on plate 9, the latch beingpulled towards arm 27 by spring 2'7e. Thus before arm 27 can rise underurge of spring 270., the latchmust' be 'removed and this is effectedbylever 19 striking the latch on the return stroke of eccentric E so thatin the lapse of time occuring, spring .'7

is able to assure return of the nut member to setting positionbefore'pawl" 10 and detent 11 re-enga'ge ratchet '3.

The nut member is "formed to control also'a totalling operation after apredetermined number of machine cycles.- To this end the nut member 1 isprovided with a cam 30 (Fig. 6A)

hereafter referred to as the ftotal cam which,

after a predetermined advance of the nut member determined by thesetting of the setting drum, stands in the path of a member actuatedfrom an arm q forming part of the machine as q are communicated to thearm 33. The links may be moved into the position shown in chain lines inFig. 9 through the agency of a lever 38 pivoted on pin 39 carried'byplate 9 andconnected by a link 40 to the link '35. a When the lever 38is in the full line position shown in Fig. 9 the links 35 and 36 are inalignment so giving rigidity to the articulated rod comprising them.

.In the position of the lever 38 shown by the chain lines in Fig. 9, thearticulated. rodbecomes limpand is unableto transmit end thrust throughthe U shapedmember 31. This is the inoperative position and is alsoclearly shown in Figs. 2 and 6A. 7

Over the free end of the arm 33 is a small bell crank 41 pivoted on pin42 which as'shown may be'thepivot pin of detent. 11. The crank 41includes an operative end 43, its other end communicated to the arm 33merely cause, by

the arm 33 abutting against the operative end 43 of the bell crank 41, arocking movement of this bell crank about its pivot .42, but when thetotal cam comes into operative position it engages the operative end 43of the bell crank 41 and the next movement of the arm q is obstructedbecause the arm 33 cannot be moved, thereupon effecting a totallingoperation in the manner described in British Patent Specification No.

Itmay be desired to stop the machine when I a total is taken. In such acase, the articulated rod is straightened for operation by the total cam30 and the. claw member 23 is in normal position to operate the cut-outplunger P,"but

50 ber 51 is in the position shown in Fig. 8- with in order-to assurethat atotal operationis ef fected before the machine is stopped, thecams 2 and 30 aredisposed in angular relation so that the operative faceof the total cam '30 leads the operative face of the cut-out cam. Whilethe counting device is being employed chine.

To this for relative movement over ,its operative'lever 19 so that theobstructor arm can be brought down bythe cut out cam 2 without causingthe claw 24 to cause a stoppage ofv the machine.

To this end the .obstructor arm, 18 is provided 7 with a slot 18athrough which it is mounted on theipivot of the lever 19. .7

"The obstructor, arm- 18 :is also connected to the, arm 27 by a strut 45provided with a pin 45a which rests onthe arm 27, the strut beingresiliently connected to the arm 27 by a spring46,

and rigidly connected to the obstructor arm 18',

for instance, by rivets as indicated at-47, while the lower end of thestrut is slotted as indicated as b sothat it may be guided'in itsmovements by the pin 20. With such an arrangement (Figs. 6A, 8 and-13)the spring-ZZdpullsup, through the agency of the arm 27 and the, pins19a and 45a, the lever 19 and-strut-45, while when thearm 27 isdepressed by cut out cam 2 the lever '19 and strut 45 are-pulled downthrough the agency of thesprings 26and 46.

' Now, when itis desired that the cut out cam 2 shall not cause the claw2.4 to operate as for instance when the total mechanism of themachine isbeing actuated from the counter, as

previously described with. particular reference 40' to Fig. 9, the lever19 is'held up so that the depression of the arm 27 results inthe'extension of the spring 26., This holding up of the lever e Theabutment lever 48 is slotted at e 48a, see

Fig. 2, for thereception of a pin 50 on a-manually operable pivotedswitchmember 51, pivoted at 510. on the plate 9. Normally the switchmemthe, abutment lever downwardly inclined. Thus the lever 19 is free totravel under the influence sion 100 '(see, Fig. 2) so that the continuedrotation of the nut member 1, after a total operation has been caused,may be utilized-to give a-preliminarylift to the feed pawl from theratchet without releasing the 'detent-thereby preventing furthermovement of the'ratchet and the'elimination of any damage in the eventof non-operation of the arm. v

In such arrangement of parts the total mechanism is operated after a.predetermined number of cycles in the machine and then the cut out cam,causes a resetting of the counter :device without the machine beingstopped. 1

Instead of utilizing the counterto cause 1.31 total operation after agiven number-of cycles end the obstructor arm 18 is mounted;

in themachine, the counter may be operated at each totalpperation ofthe. machine and the machine stopped after a given number oftotalling-operations. To this end the operationof the feedpapwl 10through the agency'of the telescopic rod .16 is eflectedbymaking theparts of the telescopic rod 16 relatively movable so that normally thereis no communication tothe feed pawl from the cam l'l but merely anextension and contraction of the rod 16, but when a totaloperationhtakes place the parts are connected to.

prevent relative movement sothat the'cam 17 operates the feed pawl.

1 The telescopic rod 16, as clearlyshown in Figs. 7 and 10, comprisestwo over-lapping parts guided relatively to one another by slotting theone part towards each extremity thereof as indicated at 16a. andproviding a pin onthe other art asindicated at 16b, to ridein the'oneslot 16a while the pin 28 passes through the'slot 16a -at;:-the otherend, the. part 1 carrying pin 16b being also slotted as indicated-at 160to straddle said pin 28. Between-the guidepins-16b and 28both parts ofthe rod 16 are formed with a notch orrecess 52 as clearly shown in Fig.7.- I When the arm 16 is contracted asshown in Fig. '7 the notches 52are in registry and are maintained in registry by a pin 53 on a latch 54pivoted at 55 carried on one part of the telescopicrod 16 as clearlyshown in Fig. 10, the pivot pin 55 serving as an anchor for one end of aspring 56, the other end of whichis connectedto the other part-of thetelescopic rod, for example by utilizing the pin 16!; asan anchoragetherefor; which spring assures the alignment of the recesses at apredetermined period of revolution of the ,mainsh aft.

When ,i the latch 54 is in rtheposition shown in Figs.- 2 and 10,thepin-53 lies in the notches 52 and .the feed pawl 10 is operated atevery cycleeof the machine. v

Now, to cause the feed pawljto be operated only on a total cycle of themachine, the latch 54 is resiliently connected, for example, bya spring5,7 to a bell crank; 58. The said crank is rocked about a .pivot 59 onplate -9 bya strap 60 actuated fromthe eccentric E, conveniently bymounting the strap. on the pin 22 carried on the plate 9. (Fig. 13) thestrap 60 having'a hooked formation indicated at 61,; see Fig. 10, whichengages a pin 62 on the back of one arm of the bell crank 58. Asindicated at 63, the support 9 of the counter device is cut away: sothat thepin 62'can operate through the support, the strap 60 beingat'the back thereof." b 1 From the foregoing itwill be understood thatat each cycle of the machine the strap 60 is reciprocated through theeccentric'E and the bell Each time'the bell crank is rocked the latch 54is "lifted and'the pin 53 removed from the recess. At this time the cam1'7 is operative but does not operate the feed pawl 10 as it merelycauses an expansion of the telescopic rod 16. Y e e When,'however, atotal operation in themachine takes place, the passage of cards throughthe attachment T stops 1 and the eccentric E ceases to rotate. Hence thebell crank 58 is not operated and the pin 53 remains in the notches 52of. the parts of the telescopic member 16 so thaton the followingoperative movement. of the cam l'lthe feed pawl is actuated.

.By such an arrangement the feed pawl 10 is only operated at each totaloperation of the machine and after a predetermined number of operationsthe cut out cam will in manner before described operate arm 27 and[cause a stoppage of the machine by actuating cut out plunger P. I II I,

When the machine is working normally, the strap is raised so that itshook 61 does not engage the pin 62 on the back of the bell crank 58,whereby the pin 53 maintainsthe parts 'of the connecting rod 16 rigidlyconnected and the feed pawl is operated from the connecting rod at everycycle of the machine as at first herein described. I

To maintain the strap 60 inoperative it may be engaged by an abutment 64passing through a slot 64a. therein and carried on a member 65 hingedlyconnected and depending from 'a manually operated lever SIS/pivoted onpin 39 aforesaid as clearly shown in Fig. 10. Q j

In the position of thelever 66 shown in full lines in Fig. 10, theabutment 64 disposes the strap so that during the reciprocation of thestrap 60 its hook 61 engages the pin 62 on the bell crank .58.

When the lever 66is rocked over to the position shown in chain lines inFig. 1D, the member 65 is lifted and the abutment 64 pulls up the strap60 as shown in chain lines. Thereafter the reciprocations of the strapare ineffective.

From the foregoing description it will be seen that a tabulator printingmachine provided with a counting device in accordance with the presentinvention can be caused to operate so as (a) to be stopped after a givennumber of cards have passed through the machine, (b) to total and stopafter a given number of cards have passed through the machine, (0) tototal after a given number of cards have passed through the machine, id)to stop after a given number of total operations.

Accordingly the mechanism provides means by which the stopping andtotalling operation of the tabulator can be controlled according to thenumber of cards fed. I I I I It should also be noted that the employmentof the total taking attachment (as described in British PatentSpecification No. 271,935) modified by including the means for operatingtherefrom the cut out 'plunger P, adds the further feature that the.machine is automatically stopped when there are no cards in it, so thatthe counter is reset at the. end of a card series.

It may also be mentioned that with the said attachment operating, thecounter can operate to stop the machine after a number of cards havepassed through the attachment: but in the combination described thesetting drum will have to be set to allow for the total operation tooccur in the number of cards.

It has already been explained that a counter construction according tothe invention is controlled absolutely by the setting of the drum 12 onthe threaded part 6a of the spindle 6.

The construction, setting and operation of the drum will now beparticularly described with reference to Figs. 3 to 6. r

The hub 67 of the setting drum carries a sprocket wheel 68 fixed, forinstance, by a set screw 69, and associated with the sprocket isa pinion70 fixed on a spring pressed plunger '71 displaceable in bearing member'72 by pressing on knob 73. The bearing 72 is provided with a tooth 74,and in the position shown in Fig. 4 this tooth engages in the teeth ofthe pinion .70 and consequently the pinion cannot move; hence thesprocket wheel 68 and the associated setting drum are locked on thespindle 6. I

To set the drum, the spring pressed plunger 73 is pressed in, therebyfreeingthe pinion '70 from the tooth 74, and. owing to the width of thepinion 70 it can be disengaged from the tooth '74 and retain itsengagement with the sprocket wheel 68.- I II I With the knob pressed inand the pinion held from tooth .74, the drum can be rotated and set onthe spindle by turning the knob '73 while pressure is retained, therebytransmitting angular movement from the pin 70 and sprocket wheel-68 tothe drum 12.

As clearly shown in Figs. 2 and 3, the numbers on the setting drum canbe read through ,an opening or window 75a which may be pro- The shutteris operated through a lever convenientlyof U shape or stirrup formindicated at 77 and pivoted at 78 on ears or brackets 79 extending fromthe front plate 9a asinost clearly shown in Figs. 2 and 3. At thebottom.of

the U-shaped-lever is a stop conveniently in the form of a pin 80, seeFig. 5. This pin lies in front of the peripheral edge of the drum 12 andis held in association with the drum by a spring 81, the upper part ofthe lever being provided with lugs 82 which engage with the underturnedportion of the shutter member 75, e r

With such; an arrangement, the U shaped lever '77 is tilted about itspivot '78 as the drum is set by axial displacement on the spindleConsequently therev is a transverse relativemovement between the shutter75 and the numbers on the periphery 13 of the setting drum. The numberon the drum visible through the window 750. of the shutter indicates thenumber of cycles in the machine to be completed before the feedpawl is]actuated to'reset the coiintingmechanismor to perform the totallingoperatioh or to stop the machine or both as hereinbefore described, andby the arrangementdescribed the pitchof the figures on the drum isgreater than the pitch of the thread 6a on spindle 6 (Fig. 4) and thuslarger figures may be employed.

I What I claim is": I r

1. in a tabulator printing machine the. combination of a threaded nutmember, a ratchet mounted coaxially therewith, a telescopic con-.nection between the nut member and the ratchet whereby the nut member.can move axially with respect to the .ratchet but cannot rotaterelatively thereto,- a feed pawl and detent whereby the ratchet isturned to a predetermined extent operable by the nut member whereby thefeed I pawl and detent are moved out of engagement with theiratchetafter a predetermined axial displacement of the nut has been eflected,

thereby permitting the nut to be reset by the reversal of the'r'atchetdue to the energy conserved in the. spring, and setting means forpredetermining the displacement of the nut neceswherein the number ofsteps executed within a given time is equal to the number of cyclesexecuted bythe machine, a spring-controlled pivoted arm adapted to beoperated by the cam after a predetermined axial displacement of the *thespring reverses the ratchet and returns th V nut member to" theresetting position.
